So, would you happen to know how popular these anomalies are generally among humans? Would it be physically and politically correct to call such a person handicapped?Basically it's like this (if I remember correctly):
1. Ovaries or testicles?
The presence of a working Y chromosomes cause the primordial sex glands to differentiate into testicles. The lack of a working Y chromosome cause them to develop into ovaries.
2. Internal and external sex characteristics
These are determined from the hormones produced by the developed sex glands. Ovaries produce estrogen which causes the development of a uterus/vagina. The testicles produce testosteron which stimulates development of a penis, a scrotum.
Thus it's possible for an XY to develop as a female, if the Y doesn't work. The individual will be infertile - I'm pretty sure about that.
